BUDAPEST, Hungary (AP) Formula One tiremaker Pirelli has concluded that Kimi Raikkonen’s tire damage late in the British Grand Prix was likely caused by external contact.

Raikkonen was set for second place in the July 16 race but his tire problem allowed Valtteri Bottas to complete a Mercedes one-two with Lewis Hamilton. The Finnish driver even looked set to lose his podium spot to his own teammate Sebastian Vettel, but in a bizarre twist he ended up third after Vettel’s own tire shredded.

The sight of two Ferraris capitulating within moments of each other led Pirelli to conduct extensive post-race tests on both cars. Raikkonen’s problem, Pirelli said in a statement Wednesday, did not come from the tire itself.

“The possible initial cause of this damage is consistent with contact against an external body, leading to a partial separation of the belt from the carcass in the two affected areas,” Pirelli said. “On no occasion was there any sign of fatigue, detachment or laceration -or even the beginning of such problems – that affected the structure of the tire. In conclusion, Pirelli can confirm that no issues have emerged connected with the tire itself.”

Last week, Pirelli said that Vettel’s shredded tire at Silverstone was caused by a slow puncture.

Vettel appeared to be heading for third place at Silverstone until his front left tire suddenly blew apart two laps from the finish. The four-time F1 champion managed to steer his Ferrari back to the pits for a tire change, and secured seventh place to cling onto his championship lead. Raikkonen’s pit stop to change his tire came just before Vettel’s.

Hamilton won to cut Vettel’s championship lead to one point. Raikkonen, who has three podium finishes this season, is fifth overall.

The championship continues at the Hungarian GP this weekend before a month-long summer break.
